Apple is poised to announce three new iPhones and possibly much more at its fall press event, starting at 10 a.m. Pacific time (1 p.m. Eastern) on Sept. 12. Follow along with AppleInsider while you watch on one of multiple sources this year, including Twitter.

Apple on Monday sent out a promoted tweet inviting select Twitter users to tune into a live stream of its upcoming Sept. 12 media event, where the company is expected to announce new products including iPhone and Apple Watch.

The increased costs of making larger displays is small compared to the extra revenues they will bring by driving greater use of the iPhone and tailoring to Apple's forthcoming video services, according to a new analysis.

Apple could start to distribute smartphones set to be unveiled on Wednesday not long after the announcement, with a report suggesting the first batch of "iPhone XS" and "iPhone XC" models could ship to customers as early as September 21 in Italy.
